Title:
HINGE STRUCTURE WITH ROTARY ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2002/077472
Kind Code:
A1
Abstract:
In a hinge structure suitable for a twofold mobile telephone, at the opening initial stage, the pushing action of an operation member is converted by a cam-cam follower mechanism into the rotational motion of a hinge. Therefore, an unexpected reaction due to the inertial force acting between two portions to be opened can be avoided to ensure a suitable opening action without any shock. Especially, the hinge is biased in an opening direction by a spring force, so that the hinge is usually kept in a closed state by bringing the clutch coupling into engagement. That the hinge can be driven in the opening direction by the spring by pushing the operation member and releasing the clutch coupling.
